Description

Overheat damaged safety socket

The invention relates to a heat-destroying safety structure and a heat-destroying safety socket and a plug, in particular to a two-conductor member of the overheat-damaged safety structure, which is fixed in a passage position by a stopper of an insulating material, and works at the working position. When the temperature is too high, the limiting member will deform and destroy the two conductive members to a disconnected position to stop the supply of current to avoid accidental ignition caused by overheating.

In order to avoid current overload, short circuit, overheating, etc. of the circuit, a fuse or a breaker is usually arranged on the circuit. When the temperature of the circuit is too high or the current is too large, the fuse is blown by the high temperature or the breaker is broken. The metal shrapnel jumps off to make the circuit open and power off, ensuring the safety of electricity.

For a related case of the fuse structure, for example, the Republic of China Invention Patent Publication No. I371053 "Temperature Fuse Connection Structure" mainly includes two terminals and a hot-melt metal, wherein the two terminals are fixedly arranged on the circuit line. The two free ends of the two terminals are respectively provided with traversable openings, and a gap is maintained between the two free ends of the two terminals without being subjected to an external force. At least one of the two terminals may be made of an elastic conductive material, and is a resilient terminal for maintaining the elastic force of the two terminal free ends from each other by the elastic force of the elastic member, the hot-melt metal passing through the two terminals The opening of the free end impacts the two ends of the hot-melt metal by riveting, expands the two ends of the hot-melt metal, and electrically connects the two free ends of the separate terminals, so that the free ends of the two terminals are inward and close to each other Contact, and the free ends of the two terminals have an elastic force that is separated to the outside from each other. When the current is overloaded, the circuit is overheated, or the ambient temperature used is too high, the hot-melt metal is heated and the temperature rises and melts and fractures, and the free ends of the two terminals are not connected to each other, so that the circuit becomes a disconnected state.

However, there are still deficiencies in the above-mentioned previous cases to be improved. The main reasons are:

1. The hot-melt metal is a conductive material, which is formed into a rivet type, electrically connecting the two free ends of the separate terminals, but when the hot-melt metal is blown, the hot-melt metal that is blown and split may be blocked by two terminals. The elastic force is detached from the original position, and it may also stick to the two terminals. If the hot-melt metal is detached from the original position, it is likely to be moved back to the two terminals due to the impact of the collision or the external force after the event. Move back to other positions that may touch the two terminals, so that the two terminals that should not be connected are in contact with each other again, and become the path state again; if the hot-melt metal portion remains stuck to the two terminals, it is sticky. Hot-melt metals are also prone to false contact between the two terminals, so that they cannot be completely powered down. In addition, the hot-melt metal is bounced off the ground, and there are opportunities to touch other electronic components around it, which is prone to short-circuit, which is still dangerous in use and needs to be improved.

2. The hot-melt metal fixes the two terminals by riveting, and needs to provide opposite openings on the two terminals, and the two openings are arranged such that the contact areas between the two terminals are relatively reduced. A small contact area causes a higher operating temperature when the current passes through the contact portion of the two terminals, especially when the two terminals are selected to have a suitable elastic force and a thinner material is selected, for example, the thickness of the two terminals is 0.2 mm. 0.4mm conductive copper sheet, the temperature rise phenomenon is very obvious.

At this time, the fire wire spring piece (43) will be away from the fire wire pin (42) by the above-mentioned return elastic force, or the neutral wire spring piece (45) is away from the neutral wire pin by the above-mentioned return elastic force. (44), changing the path position to the aforementioned disconnection position to interrupt the supply of current and avoid the operating temperature from continuing to rise. Since the above-mentioned limiting member (2H) (2I) is a non-conductive material, when the limiting member (2H) (2I) is deformed by heat, it is even broken into two, and the broken limiting member (2H) (2I) It will never cause accidental conduction, and it will be safer to implement.
